UGA BL Turbulence Measurements

A) Mini-PA2 BL Sodar: vertical range 1050m, resolution 10m/20m, time-averaged statistics every 30 min plus raw data collected continuously. Credible flow velocities include mean wind speed (u, v,w) and the variances of each of the components.        

B) Sonic anemometer/thermometer: 10Hz; 30 min averages and raw data of u, v, w; parameters to be calculated: Monin-Obukhov length, friction velocity, the three velocity variances and the virtual temperature information (mean and variances), heat flux.

C) Tethered Balloon: cup wind speed, wind direction, temperature, humidity, ozone. Low frequency sensors only, no turbulence information.
